SPECIFICATION forming part of Letters Patent No. 774,518, dated November8, 1904. Application filed January 31, 1903. Renewed August 12, 1904.Serial No. 220,462. (No model.)

To aZZ whom it rim/y concern:

Be it known that I, ARTHUR J. GREENAWAY,

of the city of Detroit, in the county of Wayneand State of Michigan,have invented certain Improvements in'Steam and Water Separators, ofwhich the following is a specification.

This invention relates to certain improvements in a steam and waterseparator adapted for insertion in the vertical portion of a steampipeleading to a steam-engine or to any apparatus where dry steam isrequired.

In the description of the said invention which follows reference is madeto the accompanying drawings, forming a part hereof, and in whichFigures 1 and 2 are vertical sections of the improved separator as seenfrom points of view separated by ninety degrees. Fig. 3 is a section ofFig. 1, taken on the dotted line in 00.

Referring now to the drawings, 1 is theshell of the separator, which ispreferably of cylindrical form, and 4 and 5 are the entry and deliverysections of asteam-pipe, connected, respectively, to the top and bottomof the shell.

7 is a ridge-plate situated near the upper end of the shell 1 andextending entirely across it. The width of the base of the ridge-plateis made considerably less than the inner diameter of the shell 1, so asto produce the channels 9. (Shown in Figs. 1 and 3.)

10 is a hollow cylinder having a diameter about equal to that of thesteam-pipe, formed integral with the bottom 12 of the shell 1 andextending from the said bottom to the under side of the ridge-plate 7and constituting practically a continuation of the delivery-section 5 ofthe steam-pipe.

13 13 are openings in opposite sides of the wall of thecylinder 10 andsituated immediately beneath the ridge-plate 7.

By reference to Fig. 1 of the drawings it will be seen that the eaves 14of the ridgeplate project beyond the circumference of the cylinder 10.Consequently any water passing down the inclined surfaces of theridge-plate will be carried beyond the cylinder and dropped into theannular space 15, existing between it and the inner surface of theshell.

17 17 are petticoat-flanges arranged one above another on the cylinder10, which serve to collect moisture from the steam coming in contactwith them and conduct it to' the annular space in a manner similar tothe eaves of the ridge-plate.

19 is an ordinary glass gage whereby the height of water in the shell isindicated, and 20 a pipe whereby the said water may be discharged. Steamentering the shell strikes the ridge-plate and is separated into' twocolumns, which pass through the channels 9, thence upward under theeaves of the ridgeplate, thence. through the openings 13 into thecylinder 10, and thence to the lower section of the steam-pipe.

It is well known that when saturated steam is made to rapidly change itsdirection of movement the globules of water held in suspension therein,being heavier than the surrounding steam, resist the change to a greaterextent thanthe lighter body, and this peculiarity is availed of in thepresent invention. The steam passes readily under the caves of theridge-plate and enters the cylinder, while the globules of water passdown the inclined sides of the ridge-plate into the annular spacebetween the cylinder and the inner surface of the shell, where itcollects.

By extending the ridge-plate entirely across the shell the whole body ofsteam is forced to pass under the caves of the ridge-plate'beforeentering the openings leading to the interior of the cylinder.

I claim as my invention In a steam and water separator, a vertical shellwith an entry and a delivery section of steam-pipe connectedrespectively to its upper and lower end, and a cylinder which extendsvertically from the bottom of the shell and forms a continuation of thedelivery-section of steam-pipe, combined with a ridgeplate whichconstitutes the termination of, and closes the upper end of thecylinder, situated under the entry-section of steam-pipe l surrounds thesaid cylinder at a, point below and extends entirely across the shell,the said the lateral openings in its well, substantially ridge-platehaving pro ecting eaves which. ex-

as, and for the purpose specified.
